Usage

General Description

3-Phenoxybenzyl 2-(4-chlorophenoxy)-3-methylbutanoate, also known as Permethrin, is a synthetic chemical compound widely used as an insecticide and insect repellent. It belongs to the family of synthetic pyrethroids, which are chemically similar to the natural insecticide pyrethrum found in chrysanthemum flowers. Permethrin is known for its broad-spectrum activity against a wide range of insects, including mosquitoes, ticks, fleas, and bedbugs. It is commonly used in agricultural settings, as well as in residential and commercial applications to control pests. Permethrin works by interfering with the nervous system of insects, leading to paralysis and eventual death. When used according to label instructions, it is considered to have low toxicity to humans and animals.

Quantitative structure activity relationship studies in pyrethroid esters derived from substituted 3-methyl-2-phenoxybutanoic acids against Culex quinquefasciatus

QSAR studies in relation to three physicochemical substituent parameters, lipophilicity, electronic and steric factors have been carried out with pyrethroid esters derived from substituted 3-methyl-2-phenoxybutanoic acids against Culex quinquefasciatus applying multiple regression analysis by grouping the esters into three based on their alcohol moiety. In the case of 3-phenoxybenzyl and α-cyano-3-phenoxybenzyl esters the larvicidal activity is mainly influenced by the lipophilic and electronic nature of the substituent at 4-position of the phenyl ring of the acid moiety. For adulticidal activity the lipophilicity of the substituent at 4-position followed by that of the substituents at 2-and 3-positions along with the steric effect are the important factors for 3-phenoxybenzyl and α-cyano-3-phenoxybenzyl esters. The larvicidal and adulticidal activities of 3,4-methylenedioxybenzyl esters are influenced by electronic factor followed by steric effect of the substituent.
